What I'm looking for

I'm seeking a collaborative, product-focused role building mobile and backend systems (Android/Flutter/.NET) in an agile team, with opportunities to work on payments, publish production apps, and grow technically.

I am a mobile app developer with 6+ years of experience building native Android apps (Java/Kotlin) and cross-platform Flutter apps (Dart). I focus on delivering user-friendly, reliable enterprise solutions and writing clean, efficient code.

I have designed and implemented controller applications that orchestrate external systems and integrated payment features using NFC and multiple SDKs. I have published production-ready applications to Google Play Store, Huawei App Gallery, and Apple App Store.

I also have backend experience with C# and .NET Core, delivering RESTful APIs and admin portals, and I use tools such as Git, JIRA, Bitbucket, Confluence, Firebase, and Google Cloud. I follow Agile workflows and participate in sprint planning and cross-functional collaboration.

I take ownership of app stability through bug fixing, performance tuning, and debugging, and I enjoy solving critical business issues while working closely with QA, design, and product teams to ensure feature completeness and a smooth user experience.
